f ul Fountain-Pen, of which the following is a specification. This invention relates generally to fountain pens, and more particularly to a novel form of straight line or other drafting pen.

` The object of the invention is to facilitate `the feeding of ink to the pen blades, and to provide a simple and efficient feeding device or this purpose.

With the above and other objects in view, as-Will appear as the nature of the invention is better understood, the same vconsists in the novel construction and combination of parts of a fountain pen, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts: Figure 1 is a view in side elevation of a drawing pen constructed in accordance With the present invention. Fig. 2 is a pers ective view showing the parts of `the pen isconnected and in their relative postions.

Fig. 3 is a longitudinal sectional-view. Fig. tits a perspective detail viewr of the. feeding tu e.

Referring to the drawing, 1 designates the tubular ink holding handle of the pen which ma be made of any suitable material that w' permit of its being flexed for the purpose of forcing-ink to the pen points, preferably of gutta-percha. longitudinally tapered, and is closed at its smaller end, its larger end 3 being exteriorly threaded so as to screw into an internally 'threaded coupling sleeve or thimble 2 with which the pen blades are assembled.

The coupling 2 comprises, preferably, a metal body bored part way of its length from one end to receive the threaded end 3 of the handle as stated, and the other end of the coupling is rectangular in cross section and forms a tongue 4 to connect with the pen blades 5. A The intermediate portion of the coupling is circular in cross section and is rovided with a milled bead to facilitate turning relatively to the handle when the coupling is to be detached therefrom or attached thereto, and on the sides of the coupling are inclined shoulders or abutments As shown in Fig. 3, the coupling 1s pro- The handle is preferablyv pose, a small knob-shaped valve 17 is j rictionally engaging with the walls of the passage or screwing into the same as may bev preferred.

The pen blades 5 are ofthe usual construction except that at their shank ends they are riveted to a spacing block 11 which is slightly removed from the shank ends so that the latter may. embrace the tongue of the coupling on the shouldered sides thereof. The ends 12 of the blades are inclined to permit them snugly to abut the inclined shoulder 7 of the c oupling when the blades are in their normal position. The blades are .secured to the tongue 4 by a set screw 13 that passes through apertures 14 in the blades and tongue,.one or more of which apertures are threaded. The points of the blades are set by the usual finger-screw 15.

The spacing block 11 is provided with a groove 16 that alines with the groove 9 in the tongue so as to embrace'the feed tube. This tube extends parallel with and between the pen blades and terminates considerably` short of the tips of the latter so that the ink escaping from the tube may flow down to the tips of the pen blades, and thus supply quantities requisite to meet the demands of any character of work being executed.

.. The pen blades are -jointed to the coupling to ermit of their being turned to one side, as indicated by dotted lines in Fig. 3, thus to allow the feed tube to be inserted into an ink well, when the pen is to be charged, without having to insert the blades at the same time. To shift the blades, it is simply necessary to loosen the set screw 13 and thereby unclamp the blades and permit them to be turned on the screw as alpivot, and after the feed tube is charged, vthe blades are again returned to their normal position.

It may be found desirable to provide means for sealing the discharge end of the feed tube during intervals between feeding of ink to. the-pen tips, so as to prevent the air from caking or hardening the ink in the tube and thereby' closing it. For this purprovided at the discharge end of the tube that is loosely supported thereat by means of a light spring 17 suitably anchored yin the en' zins snring has 'sufficient 'tenn n to maintam tevalve seated at times r is dovfing, but readily yields pressure on the inl due to the liezring of the handle, as shown in l, thereby permitting the valve to open and supply ink to thepen points. The spring is removably held in place its inner end engaging Wit i the coupling, i2, as shown in 1Wig. 3, and by this arrangement, the spring een be removed from the tube When it is' desired to till the handle with iilr, and is returned after this proeedure,

The in any preferred ne Vforce feed deviee, a pump, and dis through the tube l0' be supplied to the handle in nner, l by erdinary' niewhat in the nature oi "ged 'r'rom the handle l past the valve l? by flexing the handle in the manner above described.

F rom the foregoing description, the advantages of the invention will be readiljyT seen. The Construction is simple and permits of easy manipulation and the iilling of the feed tube without removing the blades.

Having thus described the invention what is Claimed is l. ln a fountain pen, an ink-odntaining handle, pen blades ivotally mounted with respect to the hand e, and a feed tube eX- tending from the handle toward the pointsI of the pen blade to feed ink to the latter and disposed to permit the blades .to be moved to one'side to allow ink to be supplied to the handle threugh the feed tube.

2. ln a fountain pen, an 'ink-Containing handle, a coupling, a feed tube extending. from the coupling and communicating With the handle, and pen blades pivotally mounted on the coupling so as to permit of their l being ire-ely swung l tube. to permit inn latter.

3; ln a fountain pen, an ink-conta' handle, a coupling attached thereto ari-:lp vided with abutments and with a tonga pen blades pivoted on the tongue and pe vided with portions ta engage the ab ments, and a` ieed tube for `supplying from the handle to the pen point nd tvhle is arranged at one side oi the pivot et blades to permit the latter to be tur' away from the'tube.v

in fountain pen, an inlnoontaining handle, a enabling vided With outmengts and with a grooved tongue, pen blades, a spacing block adiaoent to one end of the' blades to hold them separated to embrace the tongue of the eoupling, a set screw for clamping and pivotallymount4 ing the blades on the tongue, means on the blades for engaging the abutments, and a device mounted in the groove of the coupling for supplying ink to the pen blades.

5. ln a fountain pen, a handle, a coupling 4attaehed thereto and provided with abutments and with a grooved tongue, pen blades, 'a spacing block adjacent to one end of the blades to permit the latter to embrace the tongue, a set screw for clamping and pivotally mounting the blades von the tongue, and means on the blades for engaging the abutments. f Y

In testimoniT that I claim the foregoing as my own, I have hereto aflved my signatnnev in the presence of two Witnesses.
